ABSTRACT:
The invention provides a polarizable electrode composed of activated carbon/carbon composite having micropores among which micropores having a diameter ranging from 0.1 to 5.0 micrometers have a volume ranging from 0.1 to 1.2 cm.sup.3 /g. The composite further has a specific surface area equal to or greater than 1000 m.sup.2 /g, and a density equal to or greater than 0.5 g/cm.sup.3. The micropores having a diameter of micrometers order to be formed in the polarizable electrode in accordance with the invention, facilitate the movement of ions in the electrode. Thus, it is possible to accomplish a polarizable electrode suitable for a larger amount of current discharge.
